Identification and removal of imprecision in polynomial regression, originating from random errors (noise) in the … independent variable data is discussed. The truncation error-to-noise ratio (TNR) is used to discriminate between imprecision … dominated by collinearity, or numerical error propagation, or inflated variance due to noise in the independent variable. It is …

constant. Normally, theoretical studies of these patterns are developed without concerning a noise. In this paper we consider … FDS for a more realistic conditions and assume that the inlet concentrations are perturbed by a small noise. When the flow … rate is small, the FDS is linearly sensitive to noise at the inlet. Even weak fluctuations destroy the stationary pattern …
